LOOMI-SHUTTLE Patented March so, 1909.

Application filed December 28, 1907. Serial No. &08,357.

To all whom it may concern:

Be it known that I, ARTHUR BUoKLnn, citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inLoom-Shuttles, of which the following is a specification.

This invention relates to loom shuttles, my object being to provide ashuttle with a simple and eflicient means for receiving and retainingthe bobbin or cop, and to this end the invention consists in the novelconstruction and combinations of parts which will be hereinafter fullydescribed and particularly pointed out in the claims.

In the drawings, Figure 1 is a plan view of a loom shuttle provided witha bobbinor cop-receiving means embodying my invention. Fig. 2 is alongitudinal sectional view thereof, enlarged, as on the line 22, oiFig. 1, showing, by dotted lines, the position of the bobbin-receivingmeans when it is removed from within the shuttle. Fig. 3 is a viewsimilar to Fig. 2, including a bobbin or cop. Fig. 4 is a transverse,sectional view, as on the line 4- 1, of Fig. 2. Fig. 5 is a transverse,sectional view as on the line 5-5, of Fig. 2. Fig. 6 is a view of thebobbinreceiving spindle, detached.

1 designates a well known form of shuttle, provided with the usualbobbin receiving chamber 3 therein. The body of the shuttle 1 has,formed therein, a recess 6, through which extends a transverselyarranged pin 7 Pivotally mounted on the pin basal end 8 of a spindle 9,which extends into the chamber 3, as shown. This spindle is adapted tobe moved upon the pin 7 to a position within the chamber 3, as shown byfull lines in the drawings, and from its position within said chamber tothe position shown by dotted lines in 2. T is spindle 9 adjacent thebasil end 8 is made straight, or cylindrical for a short distance, andis then made tapering toward its free end, as shown in the drawings.Surrounding the spindle 9 near the basal end 8 thereof, is a bobbinreceiving member 10, which extends over the cylindrical portion of thespindle and a slight distance over the tapering por tion thereof, thebobbin receiving member being made to conform to the spindle, as shown.The bobbin receiving member 10 projects fixedly from a collar 11 whichsurrounds the spindle 9, and said member is 7 is the provided throughoutits length with a longitudinal slit 12, to permit the member to beexpanded against the tapering portion of the spindle 9 when the memberis moved longitudinally upon the spindle toward the pivoted end thereof.The bobbin receiving member 10 is made of spring metal, so that it in aybe expanded when the tapering portion of the spindle is projectedtherethrough, and so that it may spring back to its normal size when thetapering portion of the spindle is withdrawn.

Extending from the collar 11 is an arm 13, which extends back over thebasal end S of the spindle 9, and into the recess 6. The arm 13, extendsbeneath a transverse pin 14-, into the recess 6, and the free end of thearm is bent upwardly between the pin 1 1 and an inclined wall 15 of therecess 6. The pin 14 and the wall 15 are so located with relation toeach other and to the pin 7, that when the spindle 9 is moved to theposition shown by dotted lines in Fig. 2, the upwardly bent end of thearm 13 will engage the wall 15 and p reject the member 10 tmvard thefree end of the spindle 9, and thus permit it to contract by its ownspring action, to free the bobbin; and when the spindle 9 is moved intothe bobbinreceiving chamber 3, the upwardly bent end of the arm 13 willengage the pin 14 and draw the member 10 to hard the base of the spindle9, and thus cause the tapering portion of the spindle to expand themember 10 in a manner to engage and bind the bobbin. hus it will be seenthat when the spindle 9 is moved to the position shown by dotted linesin Fig. 2, the member lOwill be contracted and that a bobbin may bereadily placed upon the spindle 9 and member 10 and that when thespindle 9 is pressed down into the chamber 3, the member 10 will beexpanded in a manner to bind and firmly hold the bobbin upon thespindle. The bobbin receiving member, 10, may extend the entire length.of the spindle 9, 01' it may extend only part way over the spindle, asshown in the drawings.

In preparing cops or bobbins for shuttles, a paper core the full lengthof the cop or bobbin is sometimes employed, upon which the cop or bobbinis wound. Sometimes, however, in order to get a greater quantity of yarnupon the cop or bobbin, only the basal end of the bobbin is wound uponthe tube, the remaining portion being wound upon a spindle from which itis removed after the bobbin has been wound, thus providing a bobbinhaving an opening extending through the center thereof, and a tubewithin said opening and extendingpart Way therethrough.

When it is desired to use bobbins having the paper core or tubeextending the entire length of the bobbin, I would preferably extend thebobbin receiving member 10 the entire length of the bobbin. When,however, the paper core extends only part Way through the bobbin, Iprefer to have the spindle 9 project beyond the bobbin-receiving member10, so that in applying a bobbin of this character to the spindle 9 andmember 10, the free end of the spindle 9 may be projected through theopening in the bobbin not oceupied by the paper core, and the bobbinreceiving member may be projected into the paper core, in which case thebobbinis supported throughout its entire length and is held in placeupon the spindle 9 by the engagement of the member 10 With the core, asshown in Fig. 3, wherein 17 designates the bobbin and 16 the coretherein.

I claim 1. The combination of a shuttle body provided with abobbin-receiving chamber, a hollow bobbin-receiving member having alongitudinal slit in one side thereof, and being closed on the oppositeside thereof, and means for expanding the member to engage and bind thebobbin.

2. The combination of a shuttle body pro vided With a bobbin-receivingchamber, a tapering spindle, a hollow bobbin-receiving membersurrounding the spindle and having a longitudinal slit therein, andmeans for moving said member upon the spindle to ex pand the member toengage and bind the bobbin.

3. The combination of a shuttle body provided with a bobbin-receivingchamb r, a pivoted tapering spindle, an expansible bob.- bin-receivingmember surrounding the spindle, means for moving said member in onedirection When the latter is moved from Within the chamber, and meansfor moving said member in the other direct-ion upon the spindle When thelatter is moved into the chamber.

4. The combination of a shuttle body provided with a bobbin-receivingchamber, a pivoted tapering spindle, an expansible bobbin-receivingmember surrounding the spin die, an arm extending from said memberadjacent to a Wall of the shuttle and so located with relation to thepivotal connection of the spindle that said arm Will. engage said Walland move said member longitudinally upon the spindle when the latter ismoved from within the chamber, and means for engaging said arm to movesaid member in the reverse direction when the spindle is moved into thechamber.

5. The combination of a shuttle body provided with a bobbin-receivingchamber, a bobbin having a central opening therein, a tube extendingpart Way through said opening, a hollow expansible bobbin-receivingmember extending into said tube, a spindle extending through said memberand into the opening in said bobbin and beyond said member and saidtube, and means for expanding said member to engage and bind said tube.

6. The combination of a shuttle body provided with a bobbin-receivingchamber, a bobbin having a central opening therein, a tube extendingpart way through said opening, a hollow expansible bobbin-receivingmember extending into said tube, a spindle extending through said memberand into. the opening in said bobbin and beyond said member and saidtube and movable into and from said chamber, and means for expandingsaid member when said spindle is moved into said chamber.

In testimony whereof I aflix my signature in presence of two Witnesses.

ARTHUR BUCKLER.
